[Shop-talk] Electrical Question

[Bob Spidell]

Got a question for the electrician-types out there:

I needed to replace a wall switch, and when I finally determined which 
breaker
was on the circuit when I opened the breaker I still saw 40V AC on the 
two poles.

Does this mean I have a ground loop, or is there something about house 
wiring
I don't understand.  The house is old--built in the late '50s--if that 
matters, and I think
it's mostly two-wire circuits.
